The oldest system of self-knowledge

Perhaps there is not a single person who did not know or did not hear about yoga - the oldest system of self-knowledge that can lead not only to the achievement of psychological balance, but also to the improvement of the whole organism. But if thousands of articles and hundreds of treatises have been written about the spiritual component, not so much is known about the “physical” side. So, the main principle can be considered the principle of the correct posture: all asanas must be performed in strict accordance with the rules, otherwise you can not only not get the desired effect, but also harm the body. No less important is the principle of correct movement: entering and exiting the asana should be smooth (even in fast-paced Ashtanga Vinyasa Yoga): sudden movements, jerks can nullify all efforts, and in the worst case, lead to muscle strain.
